Description
The Grove-Relay module is a digital normally-open switch that can handle the current up to 5A at 250VAC for long periods of time. When the relay is switched on, the LED will light up and the relay will allow current to flow. The peak voltage capability is 250V at 10A. It is widely used in remote control, telemetry, communication, automatic control, mechatronics, power electronics and other fields.
Features
-
Digital-Switch: It has the advantages of accurate measurement, simple setting, multiple protection functions and fast speed.
-
Maximum load of a normally open interface: AC 5v@250V, DC 5v@30V.
-
Easy to connect: The easy connection is just with jumper wires, no soldering tools are required.
-
Change the level state: High-level or low-level trigger can be set by wire jumper.
-
Friendly LED reminders: When the relay works, the power prompt light will light up.
Description
We’ve released the Seeed Relay Selection Guide, it will help you choose the relay that best suits your needs.
The Relay is a digital normally open switch that controls a relay capable of switching much higher voltages and currents than your normal Arduino boards. When the relay is switched on, the LED will light up and the relay will allow current to flow. The peak voltage capability is 250V at 10A.
With the help of the Grove System, engineers and makers can easily avoid jumper-wires problems. Seeed Studio has developed more than 300 Grove modules covering a wide range of applications that can fulfill a variety of needs.
If you are interested in finding out more about the Relay, you can check our Arduino Tutorial on How to Control High Voltage Devices with Relay Modules and Types of Relay – Which one should use?
Please exercise great care when working with mains voltages – if in doubt contact a professional such as a licensed electrician for help.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before you use the product.

FAQ
What is Relay Module and how it works?
A relay module is an electrical switch that is operated by an electromagnet. The electromagnet is activated by a separate low-power signal from a micro controller. When activated, the electromagnet pulls to either open or close an electrical circuit.
